ABSTRACT:
A dishwasher has a cabinet which defines a cavity, an access opening into the cavity, and a door for said opening. A washing fluid reservoir in the cabinet beneath the cavity holds washing fluid for the dishwasher. A drain for the washing fluid reservoir is manually operable between open and closed conditions when the door is open. The drain is also interlocked with a door on the cabinet which covers the access opening such that when the door is closed, the drain, if previously open, is automatically moved to its closed condition to ready the reservoir for filling. Thus, attempting to fill the reservoir with the drain open will be effectively prevented.
